Underwater Inspection Methods

The methods used to conduct Underwater Inspections are:
  • Scuba diving -- A method that allows a more detailed examination of substructure conditions below the waterline. The diver has freedom of movement and may carry a variety of small tools with which to probe or measure.
  • Surface Supplied Air Diving -- Involves the use of sophisticated diving equipment and a surface supplied air system. This inspection method is well suited when adverse conditions will be encountered, such as high water velocity, pollution, and unusual depth or duration requirements.
The choice of which method to employ depends largely on accessibility and the required inspection detail.
